2008 Pontiac G6 oil light

If you have maintained the engine with regular oil changes, it shouldn't be a big issue. The first thing I have to ask is, do you hear any knocking or ticking from the engine when the light comes on? If not, I would suspect the oil pressure sensor is going bad. To confirm that there isn't a pressure issue, you can get a mechanical pressure gauge from a parts store and check to see what the pressure is with the engine running.

Let me know if you have additional questions.
